When a girl is so obsessed with what another girls does and she won't leave her alone. What the other girl does doesn't even concern her, and it's not even a big deal but the thirsty girl just won't leave her alone.

If a girl works at a restaurant and has to wear lingerie for a themed week, the thirsty girl is so jealous that she can't dress like that and make money so she bashes her for no reason

people who constantly dont have anything(money,food,weed,)and always show up expecting to share or be included in whatever happens to be going on at the time. weather its a cookout, or a session.. no one likes the thirsties, yet we all know several im sure

here comes slim with those dirty ass shorts on again! everytime were about to blaze, or eat! damn i cant stand these thirsties!!

A term used mostly by fags. To these fags, "thirsty" means desperate. They know the meaning of this word because the only chicks who actually get with them are thirsty and desperate as hell, and with apparently no standards.

"Hey, that girl is so thirsty desperate ! Reminds me of Taylor's last hook-up."
